Automatic refresh
• The automatic refresh mode will equalize or
balance the individual cells in the battery pack
at its peak capacity. Battery packs should be
refreshed weekly or whenever the pack no
longer delivers the same amount of work.
• To refresh your battery pack, place the battery
in the charger as usual. Leave the battery pack
for at least 8 hours in the charger.
Hot/Cold Pack Delay
When the charger detects a battery that is too hot
or too cold, it automatically starts a Hot/Cold Pack
Delay, suspending charging until the battery has
reached an appropriate temperature. The charger
then automatically switches to the pack charging
mode. This feature ensures maximum battery life.

discharging when it is used in the tool.
